Unusual Error when right-clicking

Receiving an unusual error. This error occurs if Maintenance Job Entry is open. Does not matter if I open with a current customization or a new base customization. Error occurs when right-clicking on the form not within a field. Error also occurs if right-clicking on another form not in the field (i.e. clicking in Employee form) This error only occurs if Maintenance Job Entry is open and the error message is the same whether clicking within the Maintenance Job Entry window or within another window.

Error occurs whether I am using a customization or if I create another base customization with nothing within.
